As a first step i run the '@NamedQuery Tacos.findTacosByName' to get the main object of db (Tacos), from this object i take the list parameters associated with the main object with the function 'getpstdcommonlist()' inside the class main class.
When i do the first access of the data of the list returned by the function 'getpstdcommonlist()'automatically eclipselink performs 30000 query for "fill" all the objects. The execution time on a list of 10000 records is about 48 seconds.

There is a way to work with eclispelink without executed multipe query, and use a simple inner join like the native query and fill the persistence classes?
It's normal that eclipselink use so many query to extract the data?]]>pdvmipv Mising name2013-05-23T13:05:36-00:00Re: Slow Query Extractionhttps://www.eclipse.org/forums/index.php/mv/msg/487935/1060810/#msg_1060810
